Salmonella infection is usually caused by eating raw or undercooked meat, poultry, eggs or egg products. The incubation period ranges from several hours to two days. Most salmonella infections can be classified as gastroenteritis. Possible signs and symptoms include:
- Abdominal cramps
- Blood in the stool
Signs and symptoms of salmonella infection generally last four to seven days, although it may take several months for your bowels to return to normal.
A few varieties of salmonella bacteria result in typhoid fever, a sometimes deadly disease that is more common in developing countries.
